Change No. 1:
Add three new heat load zone configurations (HLZCs) for the EOS-89BTH Dry Shielded Canister (DSC), with increased heat load up to 1.7 kW per fuel assembly, which reduces the minimum cooling time to 1 year.
Change No. 2:
Add a variable-lead thickness EOS-TC125 for transfer with the EOS-89BTH DSC.
Change No. 3:
Add ATRIUM 11 fuel as an allowable content in the EOS-89BTH DSC. Reran the limiting GNF2 and ABB-10-C cases to reduce the statistical uncertainties and increase the enrichment limits.
Change No. 4:
Update the criticality evaluation to allow short-loading the EOS-89BTH DSC with less than 89 fuel assemblies to increase the enrichment limits.
Change No. 5:
For the technical specifications; a revision to allow for phased array automated ultrasonic testing and to utilize a single pass high amperage gas tungsten arc weld or multipass gas tungsten arc weld on the outer top cover plate.
Change No. 6:
For the technical specifications; a revision to reduce EOS-37PTH HLZC 1 and 2 time limit for transfer to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
Change No. 7:
Incorporate a method to determine new loading patterns based on the maximum allowable heat load per DSC and per location specified in the technical specifications (TS). All HLZCs and time limits for transfer for the EOS-89BTH DSC transferred in the EOS-TC125 are moved from the technical specifications to the updated final safety analysis report (UFSAR) chapter 2.
Change No. 8:
For the single bottom forging EOS-DSCs, waive the fabrication pressure test requirement.
Change No. 9:
TS and UFSAR changes for consistency among DSC types and terminology clarifications.
In addition to the nine changes requested by applicant in their letter dated March 21, 2021, the applicant requested three additional scope changes in letters dated October 22, 2021, June 29, 2022, and September 30, 2022. The three additional scope changes include:
J. Shepherd Additional Scope Change No. 1:
UFSAR revisions associated with transfer cask lifting heights and consideration of severe weather.
Additional Scope Change No. 2:
UFSAR revisions associated with maintaining water in the annulus.
Additional Scope Change No. 3:
Design changes to the Matrix Loading Crane (MX-LC).
